Factorized Tree-level Scattering in AdS_4 x CP^3

TL;DR

This paper investigates tree-level string scattering in AdS_4 x CP^3, computing multi-point amplitudes and showing no particle production, thus contributing to understanding integrability in AdS_4/CFT_3 duality.

Contribution

It provides explicit calculations of bosonic scattering amplitudes in AdS_4 x CP^3, revealing integrability features at tree level in this new duality system.

Findings

All bosonic four-, five-, and six-point amplitudes computed.

No particle production observed in the scattering processes.

Supports integrability of the string theory in this background.

Abstract

AdS_4/CFT_3 duality relating IIA string theory on AdS_4 x CP^3 to N=6 superconformal Chern-Simons theory provides an arena for studying aspects of integrability in a new potentially exactly solvable system. In this paper we explore the tree-level worldsheet scattering for strings on AdS_4 x CP^3. We compute all bosonic four-, five- and six-point amplitudes in the gauge-fixed action and demonstrate the absence of particle production.
